I ordered a Rob Roy which is a Manhattan but with Scotch, the bartender looked at me like I fell out of a tree, I asked if he knew how to make it, he said he did, I knew he didn't and it tasted like crap, but I suffered through it rather than risk making a scene.
First off service at the Thunder Bar is a joke, and that fact that a bar in a Casino has a long line to order a drink means management does not have a clue how to make money.
